@ alt 'whom it may concern i Be it known that l, @Hannes E. @LARI-r, a citizen of the United States, and a resident o Douglas, in the county oi' onverse and State of Wyoming, have invented a nevi7 and improved Radiator, of which the following a full, clear,l and exact description.

My invention relates to radiators and it has for its object to provide one which may be readily taken apart to make repairs, the radiator being constructed with a member having a recess in which there is a gasket, a second member of the radiator disposed against the gasket and having a tongue disposed in a groove in the irst member which extends longitudinally thereof so that a tight joint is obtained between the two members when they are pressed together.

Additional objects of the invention will appear in the following complete specication, in which the preferred form oi? the invention is disclosed.,

in the drawings Similar characters of reference indicate corresponding parts in all the views, in which-f Y Figure 1 is a sectional view on the line 1--1 of Fig. 2; Fig. 2 is a sectional view on the line 2-2 o Fig. 1; andFig. B is a plan view on a reduced scale of one of the air fins By referring to the drawings it will be seen that the radiator is provided with a middle portion 5, having outer side walls 6, and inner side walls 7, spaced therefrom. The space between the inner side walls 7 and the outer side walls 6 is inclosed at the front and rear of the radiator by walls 8, leaving the front and the rear of the radiator o en between the inner side plates 7. The side plates 7 are connected at their to by an upper plate 9, andthe said inner si e plates 7 are connected at their bottom by bottom plates 10. The up er and lower plates 9 and 10 have openings 11 therethrou h, with tapped portions 12, providing shoulders 13, against which gaskets 14 may be disposed, so that when the water tubes 15 are disposed vertically, with their threaded terminals 16 disposed in the openings 11 in the u per and lower plates 9 and 10, nuts 17 may turned home on the threaded terminals 16, of the water tubes 15 to press the gaskets 14 to make water-tight ,joints between the terminals 16 of the water tubes 15 and the upper and lower lates 9 and 10. It will be understood that t ese water tubes Speeieation of Letters Meent.

ma;v be conveniently replaced by removing the nuts and that when there is any leakage between the water tubes 15 and the plates 9 and 1G, the nuts 17 may be removed to ermit the removal of the gaskets 14. Bexore these water tubes, which are preferably constructed of drawn copper tubing, are disposed with their terminals 16 in the openings il, the air ns 18 are disposed between the upper plate 9 and the lower plate 10, these air 18 having holes 19 cut therein, with depending flange portions 20 around the holes 19, the-flange portions 20 servingto hold the air ns 18 spaced apart. When the openings 19 have been cut in the air fins 18, so that they will be disposed in alinement with the openings 11 in the upper and lower plates 9 and 10, and a sufficient number of these air fins 18 are disposed on each other, to substantially lill the space between the upper and lower planes 9 and 10, the air ins are dipped in solder, to hold them together. When these air fins are then disposed between the upper and lower plates 9 and 16, and the water tubes 15 are secured with their terminals in the openings 11 in the upper and lower plates 9 and 10, lit will be seen that the central or middle portion of the radiator will be completed, and it will merely be necessar to provide the reservoirs at the top an bottom of the radiator. At the top of the middle portion 5 of the radiator there is a recess 21, there bein a gasket 22, which is normally disposed in t is recess 21. There is also in the top of the middle portion of the radiator, at its front, a groove 23, for receiving a forwardly extending tongue 24 on the upper reservoir member 25, of the radiator. This upper reservoir member 25 also has a depending flange 26, which extends all around the bottom of the upper reservoir member 25, and which is adapted to extend down into the recess 21, and against the gasket 22, to make a tight joint all around the radiator between its middle portion 5, and the upper reservoir member 25. The rear of the u per reservoir member 25 is held down relatively to the middle rtion 5 of the radiator by the bolt 27, w ich is disposed through the openings in the lugs 28 the bolt 27 being rovided with a nut 29 by which means the ugs 28 are held toward each other, and the upper reservoir member 25 is held down on the middle portion 5 of the radiator. The lower reservoir member 30 is secured in position relatively to the middle portion 5 of the radiator in substantiall the same manner. The lower plate 10 o the middle portion 5 of the radiator has a tongue 31, which extends forwardly, and into a groove 32 in a. member 33, which extends upwardly at the front of the lower reservoir member 30, the lower reservoir member having an inwardly extending member 34, with a recess 35 therein, in which is disposed a gasket 36, against which presses down the depending flange 37 on the lower plate 10. In this way the front of the lower reservoir member 30 will be held secure relatively to the middle portion 5 of th'e radiator, and a water-tight joint will be made between the lower reservoir member 30 and the plate 10. It will therefore be seen that when the front of the lower reservoir member 30 is held relatively to the front of the middle portion 5 of the radiator by the bolt 38, which is disposed in the openings in the lugs 39 and 40, the nut 41, which meshes with the thread on the bolt 38, serves with the bolt to press the lugs 39 and 40 together, to securely hold the lower member 30 in position relatively to the middle' portion 5 of the radiator. It will be seen that the upper reservoir member 25 and the lower reservoir 'member 3() may be conveniently removed, to permit of the removal of the water tubes 15, so that any possible leaka e in the radiator may be quickly repaire by the replacement of the gaskets or the replacement of the water tubes, s ould the water tubes become dama ed. An overflow pipe 42 is provided, whic enters the upper reservoir member 25, and extends upward therein, this overflow member 42 being connected with its companion member 43 by a coupling-44, this coupling 44 being provided so that the part 42 of the overow pipe may be disconnected from the part 43 of the overflow pipe, to readily permit the removal of the upper reservoir member 25, from the middle portion 5 of the radiator. The pipe to the cylinder jacket is shown at 45, and the lead pipe from the cylinder jacket is shown at 46. There is a drain cock 47 in the bottom of the lower reservoir member 30, and screws 48 are provided by which means the lower reservoir member 30 may be secured to the frame of an automobile.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a radiator, a member having a recess extending around the top of the member, there being a groove in the top of the member extending longitudinally thereof, a

asket in the recess, a second member havlng a tongue disposed in the groove, the second member being normall disposed against the gasket and means or holding the second member in place.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
